| Abstract Scope |
Combining friction stir welding principles with extruded feedstock, additive friction stir deposition (AFSD) is an emerging solid-state additive manufacturing process that allows for rapid layer-by-layer deposition of fully dense material. AFSD requires no thermal input, with friction between substrate and spinning feedstock leading to heating and severe plastic deformation to achieve bonding. Aluminum alloys are of particular interest for AFSD given their high strength-to-weight ratio and low processing temperature requirements. To enable exploration of AFSD process-structure-property relations, this study utilizes Gleeble hot torsion to replicate the elevated temperatures and rotational deformation characteristic of AFSD. AA6061 feedstock-type material is deformed under torsion following representative AFSD thermal profiles. Resultant microstructures are examined via microhardness, electron backscatter diffraction, and profilometry-based indentation plastometry, and compared against actual AFSD material built using similar process parameters. Findings support Gleeble hot torsion as a promising tool for studying AFSD as the process becomes more widely adopted. |
